2004 Mazda Tribute V6 Misfire

Post by samjesse »

Hi
Not sure what to make off the fire line slopping in the positive territory and going negative. does that mean the KV needed to fire the plug changes polarity once the spark plug gap gets ionized? but why?
I think this car is the same as Ford Escape.
The data file is captured with a the power probe placed on cylinders 6, 5 and 4 respectively, notice the gaps between each group of data capture showing the time to move the probe from the top of one coil to the other.

Thanks
